.LGHUt-EYE'ITS, A. GQREOI'EATION OF BOX-MOTION CONNEGTER.

Application filed November 25, 192 Se ial, No. 752,222.

To a l], whom it may con 0cm:

lie it known that I, Armani) lb. Moinui'im, a citizen of the UnitedStates, residing at orc a; n the county of Worcester and State ofMassachusetts, have invented a new and useful Box-Motion Connector, ofwhich the following is a specification.

This invention relates to improvements in box motions and moreparticularly to motions of this type which are employed on loomshavingdrop boxes on both ends.

it is the principal object of my invention to provide a two part drivingconnection between the box motion at one end of the loom and theactuating mechanisn'i for the boxes at the opposite end of the loom socon structed' that proper adjustment may be made to permit the boxesactuated by the driving connections to be properly aligned with the raceof the lay.

, It is afurther object of my invention to provide a safety device toprevent damage to the boxes for the box motion should shuttle beimproperly boxed when the boxes start to move. 1

Because of the construction set forth hereinafter I am enabled toconstruct box motions without knowledge'of the width of the looms towhichthey are to be applied. It has been the practice heretofore inmotions of the type shown herein to provide the box motion with adriving shaft formed in one piece, one end of the shaft being connectedto the box motion and the other end ex-v tending across the'loom, andbecause of this construction it has not been possible to bulld boxmotions without knowing the width or length of the looms to which theywere to be applied. It is therefore a further object of my invention toprovide a box motion acting through a rotary shaft which shall beapplicable with equal facility to looms of difierent widths.

Vith these and other objects in view which will appear as thedescription proceeds, my invention resides in the combination andarrangement ofparts hereinafter described and set forth in the claims.

In the accompanying drawings wherein I have shown a convenientembodiment of my invention,

Fig. 1 is an end elevation of box motion parts sufficient to show theapplication of my invention thereto,

Fig. 2 is a front elevation of the construction shown in Fig. 1,

l i g. 3 is an enlarged vertical section taken through coupling on line33 of Fig. l, and

Fig 1 is a vertical section on line 1- 1 of Fig.

Referring to the drawings it will be seen that I have provided a loomframe 10 to which is secured a frame 11 through which extendsdrivingshaft 12 of the loom. A master gear 13 on said shaft is provided withsections of teeth indicated at 1% which cooperate at proper times withthe actuating pinions for the box motion, two of said pinions beingshown herein as at 15 and 16, respectively. The upper pinion 15 isoperative through connections not shown to actuate the boxes on that endof the loom adjaoent to the gear 13 and the lower gear 16 is operativethrough mechanism to be described to actuate the boxes on the remote endof the loom.

Associated with the gear 16 is a sliding tooth 1'? which is movableunder control of the angle lever 18 toward and from the master gear,said tooth when in alignment with the master gear initiating therotation of gear 16 by one of the segments 11 and when out of alignmentwith the master gear permitting said segments to pass the gear 16without actuating the same. The position of the tooth 17 is controlledby means of link 19 which may be actuated by any approved patternmechanism. The matter thus far described is'very well known in the artand forms no part of my present invention.

The gear 16 is fastened to the outer end of a shaft'section 30, causingthe latter to undergo a half revolution each time said pinion 16is'actuated by the master gear.

The inner end of said section 30 may be reduced as at 31 and has securedthereto a coupling member 32 by means of a shear pin 33. Said coupling32 is. further provided with a flange 3 1 in which are formed arcuateslots 85 through which extend a plurality of bolts 36. Said bolts 36extend through a flange 87 formed on a second coupling member 38 whichis keyed or otherwise secured to the reduced end 39 of a shaft section40. The flanges may be of substantially the same proportions and arefastened together tightly by means of the bolts 36, thus requiringthesections 30 and 40 to move in unison so long as the shear pin 85 isnot disrupted. In order that the flanges may be properly related to eachother the reduced end 31 extends into the bore 41 of coupling portion38, thus centering the coupling portions. The section 30 is supported bybearing 49 carried by the frame 11.

As indicated in Fig. 2 the farther end of said shaft 40 extends througha bearing 42 and has secured thereto acrank arm 43 from which extends astud or driving pin 44. Pivoted to the loom frame as at 45 is a lever 46one end of which is slotted as at 47 to receive the driving pin 44 andthe other end of which is connected as by link 48 to the box lifter rod(not shown) for the adjacent boxes.

In operation the half rotation of the shaft sections 80 and 40 cause thecrank 43 to move through 180 to move the lever 46 from the full lineposition shown in Fig. 1 to the dotted line position. Should the shuttlebecome caught between the lay and the boxes as the latter move the pinwill be sheared off and thus protect the shuttle and the shuttle box. Ihave shown my invention applied to a loom having two shifting shuttleboxes on each end thereof but the invention is not limited to such atype of loom. VJhen it is desired to effect angular adjustment of theshaft sections 30 and 40, the bolts 36 are loosened and the couplingmembers adjusted 'ith respect to each other, the end of the section 30which projects into the bore 41 serving to align the coupling memberswhen the bolts are loose.

From the foregoing it will be seen that I have provided a box motionwherein the connection between the box motion and the remote boxes canbe disrupted when occasion requires. Also, adjustment between the shaftsection may be obtained conveniently and the parts held in alignmentwhile the adjustment is being made. Furthermore, the shorter section 30makes it possible to build the box motion complete with the pinion 16 inplace independently of the length of the loom to which the motion is tobe' applied. the section 40 varying with the particular loom to whichthe motion is attached Having thus described my invention it will beapparent that changes and modifications may be made therein by thoseskilled in the art and I do not wish to be limited to the details hereindisclosed, but what I claim is:

1. In a box motion applicable to looms of varying widths, box liftingmechanism, means to actuate said mechanism, and connection between saidmeans and mechanism, said means con'iprising a portion of fixed andinvariable length associated permanently with the means to actuate thelifting mechanism, and said connections comprising also a second memberhaving driving connections with the first member and being of variablelength depending upon the length of the loom to which said box motion isto be applied.

2. In a box motion for looms, box lifting mechanism, means to actuatesaid mechanism, and a driving connection between said means andmeclmnism, said means including a shaft formed in two parts, a couplingformed in two parts, one part of the coupling being connected to onepart of the shaft and the other coupling being connected to the othershaft, and means to adjust the angular position of said coupling memberswith respect to each other.

3. In a box motion for looms, mechanism to lift the boxes, means toactuate said mechanism, and connections between Said means and mechanismincluding aligned shaft sections, a coupling member secured to theadjacent ends of each of said shaft sections, one of said shaft sectionsextending through the member secured thereto and into the other member,and means to adjust the angular position of the flanges with respect toeach other.

4. In a box motion for looms, box lifting mechanism, box motion toactuate the same, and driving connections between the box liftingmechanism and the driving mechanism, said connections including a twopart shaft, a coupling to connect said shaft parts together, and a shearpin connecting said coupling to one of the shaft parts to be disruptedwhen free motion of the shafts is resisted.

5. In a box motion for looms, a box lifting mechanism, a regularlyrotating master gear, a pinion to be actuated by the gear, a shaftsection on which said pinion is mounted, a second shaft sectionoperatlvely connected to said box lifting mechanism, and means common tosaid shaft sections to connect the same together and cause them torotate in unison.

In testimony whereof I have hereunto afiixed my signature.
